Old Synopsis: [linux] [panic] kernel crash by linux.ko module with nooptions COMPAT_FREEBSD32
New Synopsis: [linux] kernel crash by linux.ko module with nooptions COMPAT_FREEBSD32
State-Changed-From-To: open->analyzed
State-Changed-By: arundel
State-Changed-When: Sun Jan 30 18:13:13 UTC 2011
State-Changed-Why:
We have two possibilities in order to fix this issue:
1) Add something like the following somewhere in sys/amd/linux32:
#ifndef COMPAT_FREEBSD32
#error "linux emulation requires COMPAT_FREEBSD32 \
option for non 32 bit architectures"
#endif
2) Find a way to avoid the freebsd32_exec_copyin_args() call in
linux32_machdep.c. I believe this is the only place in the sys/amd/linux32
code that depends on sys/amd64/ia32 code.
NB: I've removed the panic tag from this PR. I was able to reproduce the issue,
however a panic didn't occur. The problem is that
freebsd32_exec_copyin_args() wasn't compiled into the kernel and loading the
linux kernel module thus fails.
